Modular Programming Concepts

What is a function in modular programming?

• A block of code that performs a specific task and can be reused throughout the program.

• A variable that stores multiple values

• A conditional statement

• A type of data structure

Explain the difference between subroutines and procedures.

• Subroutines are specific to a particular programming language, while procedures are universal

• Subroutines can only be called once in a program, while procedures can be called multiple times

• Subroutines are a generic term for any sequence of instructions that can be called multiple times within a program, while procedures are a specific type of subroutine that returns no value.

• Subroutines and procedures are interchangeable terms with no difference

What are arguments in the context of modular programming?

• Values passed into a function or module when it is called

• Data types used in the program

• Comments within the code

• Variables declared within a function

Define parameters and their role in modular programming.

• Parameters are not necessary in modular programming

• Parameters are used to define the structure of a module

• Parameters are only used in object-oriented programming

• Parameters allow for passing values into a module or function.

Differentiate between global variables and local variables.

• Global variables are accessible and modifiable by any function within the program, while local variables are only accessible and modifiable within the function where they are declared.

• Global variables are only accessible and modifiable within the function where they are declared

• Local variables are accessible and modifiable by any function within the program

• Global variables are only accessible within a specific function

Why is it important to avoid using global variables in modular programming?

• To improve code reusability and maintainability

• To avoid code complexity and unexpected side effects, and to improve code reusability and maintainability.

• To increase the likelihood of unexpected side effects

• To make the code more organized and readable

What is the significance of local variables in modular programming?

• They are only used for debugging purposes

• They have no significance in modular programming

• They help in encapsulating data and preventing unintended changes from other parts of the program.

• They make the program run faster

How are functions and subroutines related in modular programming?

• They are completely unrelated concepts

• They are both used to create reusable code blocks and improve the organization and readability of the program.

• Functions are used for input/output operations while subroutines are used for mathematical calculations

• Functions can only be used in object-oriented programming while subroutines are used in procedural programming

Explain the concept of scope in the context of local variables.

• Scope is the name of the local variable

• Scope in the context of local variables refers to the specific part of the program where the variable can be accessed and used.

• Scope refers to the color of the local variable

• Scope is the size of the local variable

Discuss the advantages of using modular programming in software development.

• Modular programming leads to more bugs and errors

• Modular programming makes code harder to understand

• Modular programming slows down the development process

• Modular programming provides easier maintenance, code reusability, and better organization of the software development process.
